There I want to receive multiple bytes with one transfer. For inspiration I used the I2C003_Example1_XMC11 provided by Infineon. With the master (which is actually a Cortex-M3 microcontroller) I try to read multiple bytes from the XMC in one transfer, but it is not working.I have to ...

(IDFGH-8147) Multiple read command in a single I2C command link times out or return garbage without error. (IDFGH-8147) Sep 1, 2022 Contributor Author X-Ryl669 commented Sep 1, 2022 • edited Ok, so here's the actual result on the console: E i2c: I2C prog 0: cmd idx: 0 E...
The TXFIFO register of LPI2C only has one byte length, and if the length of the data that needs to be read exceeds 256 bytes, it needs to be written to TXFIFO multiple times. Signed-off-by: Fedor Ross <fedor.ross@ifm.com>2024...
Hi, I am using I2C lpc54618 for connecting multiple sensors on the same I2C bus with 3.3K pull-up resistor(3.3v). I am able to read and write data
